HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 769,288, datedSeptember 6, 1904.

' Application filed October 26,1903. Serial No. 178,662 (No model.)

.Stackers, of which the following is a specification.

This invention relates to hay-stackers, and

' it has for its object to provide a machine of this class which shallbe simple in construction, durable, easily manipulated, and thoroughlyefficient for the purpose of elevating the loads of hay and depositingthe same upon a stack.

A further object of the invention is to so construct the device that abase-frame of comparatively small size may be utilized, while at thesame time the load may be raised to elevate it to a considerable height.

With these ends in view the invention consists in the improvedconstruction, arrangement, and combination of parts which will behereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being understood, however, that changes andmodifications may be made within the scope of the invention andespecially .with regard to the size, proportion, and exact manner ofassemblage without departing from the spirit of the invention orsacrificing the utility of the same,

In said, drawings, Figure 1' is a perspective view showing'theimprovedhay-stacker inposition for receiving a load. Fig. 2 is a perspectiveviewshowing the hay-stacker with the carrier in an elevated position. Fig. 3is a detail view of the free end of the carrierframe, showing thecarrier-head in tilted position. Fig. lis a perspective detail view ofthe hoisting and lowering mechanism. Fig.

5 is a detail view showing the hinge connection of the tilting framewith the carrierframe. Fig. 6 is a detail view ofone ofthe rope-guidingrollers. Fig. 7 is a detail view taken transversely through the sillsand looking in the direction of the uprights 5 and the crolss-piecessupporting the drum or windingree Corresponding parts in the severalfigures areindicated by similar numerals of reference. The base-frame ofthe machine is composed of a pair of sidepieces 1 1, which are connectednear their rear ends by a pair of cross-pieces 2 3, supported edgewiseupon the side pieces.

The front ends of the latter are connected by,

a cross-piece, which is mortised into the said side pieces. The lattersupport a pair of uprights 5 5, the lower ends of which are framed intothe side pieces 1 1, closely adjacent to the cross-piece 3, the upperends of said uprights being connected by a cap-piece 6, the ends ofwhich are mortised into the said uprights. The latter are each providedwith a vertical transverse slot 7 Inclined braces 8 8'connect theuprights 5 with the side pieces of the base-frame, and the latter areprovided near their front ends with horizontally-disposedtransverse'slots 9.

The main carrier-frame is composed of side pieces 10 10, which areconnected near their free ends by a cross-piece 11 and near their innerends by a cross-piece 12. When I refer to the inner ends of thecarrier-frame, I mean the end which is connected, as will be presentlydescribed, with the uprights 5 of the supporting-frame. WhenI refer tothe under side? of the carrier-frame, I'have in mind the position of theframe when ready to receive a load, as shown in Fig. 1 of the drawings,the cross-piece 11 being secured to the under sides of the arms or sidepieces 10 of the carrier-frame near the free end of said arms, while thecross-piece 12 is secured to the upper. sides of said side pieces toconnect 'and to space the latter suitably apart.

ed adjacent to the outer sides of the side pieces 10 upon the ends of atransverse tubular shaft 15. The inner ends of the side pieces 14: areconnected by a cross-piece 16, which extends underneath the side piecesof the carrierframe. Across-bar17 connects the side pieces or blocks 14:above the carrier-frame. Suitably secured to the side pieces 10 of thelatter are a pair of beveled blocks 18, which serve as stops when thecarrier-head is tilted rearwardly, as shown in Fig. 3 of the drawings.The said carrier-head includes the longitudin al teeth 19, which arebolted to the under side of the cross-bar l7, and the upright teeth,which may be bolted to the teeth 19 and to the front side of thecross-bar 17, a reinforcingbar 21 being secured to the teeth 19 in frontof the lower ends of the teeth 20.

It will be observed that by the construction and arrangement of thecarrier-head which has been just described the cross bars 16 and 17 willprevent the head from swinging downwardly beyond the proper limit andwill retain said carrier-head in position while a load is beingelevated, while the blocks 18 serve as stops to prevent excessivemovement of the carrier-head in the opposite direction, as in the act oftilting, while the load is being discharged upon the stack.

22 designates an upright which is disposed intermediately between theuprights 5 of the main supporting-frame and the lower end of which isbolted securely to the cross-piece 3, while said upright, which extendsabove the cap-piece 6, is mortised into and strongly connected with thelatter. Braces 23 also connect the said upright with the cap-piece 6.

This upright carries at its upper end a pulley 24:, having a guard orcap 25, which serves to.

retain in position a hoisting-rope 26, one end of which is made fast tothe upper side of the cross-piece 11 of the carrier-frame, while theother end, after passing over the pulley 24:, extends downwardly and issecured to a drum or winding-reel which is mounted in suitable bearingsupon the cross-pieces 2 and 3, between which the said reel isaccommodated. This drum or reel comprises a shaft 27, upon which ismounted a cylinder 28, having end flanges 29 and 30 and acentrally-disposed band-wheel 31, whereby the reel is divided into twoseparate compartments. The hoisting-rope 26 is connected with the partof the drum adjacent to the flange 30, and the draft-rope 32 isconnected with the part of the drum adjacent to the flange 29 and iswound in the opposite direction to the hoisting-rope. Hence when draftis applied to the rope 32, whereby it is unwound from the drum, thelatter is rotated and the hoisting-rope 26 is wound thereon, as will bereadily understood. The crosspieees 2 and 3 are extended at one side ofthe base-frame and serve to support a platform 33, having a slot 34, inwhich is pivoted a hand-lever 35, the lower end of which is connected bya hooked rod 36 with a steel strap 37, which passes over the wheel orfrictionpulley 31 and has its opposite end made fast to a suitable pointof attachment, such as one of the base-beams 1. Means for applyingdraft, such as a whiiiietree 38, is connected with the end of thedraft-rope.

Pivotally connected with the front side of the cross-piece 3 is abell-crank lever 39, one arm of which is connected by a rod to with thehand-lever above the fulcrum of the latter. The other arm of thebell-crank 29 is connected by a rod 41 with one arm of a T- shaped latchd2, which is pivotally connected with one side of the upright 22.Suitably attached to the front side of the latter a short distance abovethe latch 12 is a stop-block -13.

Suitably bolted to the front side of the cap 6 is a cross-bar 44, at theends of which are journaled a pair of guide-pulleys Asimilar cross-bar16, connected with the upright 22 near the upper end of the latter, isprovided at the ends thereof with guide-pulleys 17, which are inalinement with the guide-pulleys 15.

4:8 designates a weight or a box adapted to contain weights sul'licientto counterbalanee the weight of the carrier-frame. This weightbox isattached at its ends to a pair of ropes 419, which pass over theguide-pulleys 15 17, and thence in a forward and downward direction tothe front end of the carrier-frame when the latter is in the positionshown in Fig. 1, the ends of said ropes being secured to the transverseshaft 15, which pivotall y connects the carrier-frame with thecarrier-howl.

Hingedly connected with the under side of the cross-bar 12 at the innerend of the carrier-frame are the side pieces of a frame which Idesignate the tilting frame, said side pieces being connected by across-piece 51 and by a shaft 52. the ends of which extend into and areslidable in the slots 9 near the front end of the base-frame.

Suitably secured to the front side of the stop-block 43 is the lower endof a strap 53, which extends in front of the cross-bar 11 and the upperend of which suitably secured to the front side of the upright 22. Thisstrap serves to reinforce the parts connected thereby and also as aguiding means for the weightbox 18 when the latter is at the upper limitof its movement.

Upon the upper side of the cross-bar 11, in alinement with theweight-carrying ropes 19, are mounted a pair of guide-rollers 51, whichengage the said weight-carrying ropes to avoid wear by friction upon thelatter. Similar rollers 55 are mounted upon the cross-piece 3 to engagethe side members 50 of the tilting frame.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art'to which it appertains.When themachine is in the position illustrated in Fig. 1, the load to beelevated may be deposited upon the carrier by means of an ordinarygathering-rake. When the load is in position, draft is applied to thedraft-rope, which results in unwinding the same from the winding-drumupon which the hoisting-rope is simultaneously wound, thus elevating theloaded end of the frame and simultaneously causing the shaft connectingthe side members of the tilting frame to move forwardly in the slots 9near the front end of the base-frame. loaded end of the carrier is beingelevated the shaft 13, connecting the side members of saidcarrier-frame, will gradually move upwardly in the slots 7 of theuprights 5, the tilting frame meanwhile serving to tilt thecarrier-frame until the latterassumes its elevated. and approximatelyvertical position. (Illustrated in Fig. 2.) When the carrier-framereaches this position, the shaft 13v passes into engagement with thelatch 42, upon which it is supported, further movement in an upwarddirection being checked by the stop-block 43, the location of the underside of which is slightly below the upper ends of the slots 7 of theupright 5. While the carrier-frame is thus being elevated, theweight-box 48 descends and assists in the elevating operation to theextent of counterbalancing the weight of the carrier-frame, and whilethe latter is being elevated the rollers 54 upon the crossbar 11 willengage the weight-carrying ropes 49, which are thus temporarily passedaround the guide-pulleys 45, as will be seen in Fig. 3 of the drawings.When the carrier-frame reaches its elevated position, the weight of theload will tilt the carrier-head to the position illustrated in Fig. 3and the load will thus be guided in a rearward direction onto the stackwhich is being built. It will be observed that the frame is nowsustained inan elevated position by the latch member 4C2. In order torelease the frame and permit it to drop to its initial position, it isonly necessary to manipulate the hand-lever 35 by thrusting the'upperend of said lever in the direction of the winding-drum, The intermediateconnecting-rods 4:0 and 41 and bell-crank lever 39 will thereby beoperated to swing the latch member 42 from under the shaft 13, thuspermitting the frame to drop, but at the same time thestrap 37, whichconstitutes a friction-brake, will be tightened upon the band wheel orfrictionwheel 81, and the operator is thereby enabled to perfectlycontrol the rapidity of the descent of the carrier-frame and itsrestoration to the initial position. (Shown in Fig. 1.)

It is to be understood that in the construc tion of myimprovedhay-stacker the parts are to be strongly braced and jointedtogether in any suitable manner and that bracing devices, bolts, and thelike may be used whenever desired. By the construction herein de- As theis simple, inexpensive, and practically useful for the purposes of theinvention. 3
